CR-M1431is a blooming free retardant developed for glass fiber reinforced PA66. This product can be sold as powder or as masterbatch. It has great retarding efficiency，and the dosage level required to achieve the same UL V0 ratings is10-20% lower than those of Clariant products. What’s more, the flowing behavior and mechanical properties of the retarding resin is improved, compared to resins with Clariant retardants.

1. Materials

4.Summary

CR-M1431has outstanding blooming stability，can be stable up to 3000hrs under double 85 testing conditions。It also has superior retarding efficiency, and the dosage level required is lower, and in return the application cost is lower. What’s more, the flowing behavior and mechanical properties of the resins treated with CR-M1431 are notably improved, compared to the resin with Clariant products.
